PM89305: MAPSID IN A CHILD ENTITY TO A PARENT ENTITY USING AUTO-ASSIGNED IDENTITY FAILS WITH DUPLICTE INSERT SQL.

Fixes are available

APAR status

Closed as program error.

Error description

When inserting ObjectA in to a database with ObjectB attached
to it, ObjectA is inserted twice resulting in a sqlstate 23505
constraint violation.

The Primary Key of ObjectC is autogenerated and is used in
ObjectA as the Primary Key.  It is also used as part of
ObjectB's Primary Key.

In testing, if you use the same setup while replacing the
combined Primary Key of ObjectB with a single Primary Key, the
test case runs without errors.

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server V8.0.0, V8.5.0, and V8.5.5 who make  *
*                  use of MapsID and auto-generated identity.  *
****************************************************************
* PROBLEM DESCRIPTION: MapsId in a Child entity to a Parent    *
*                      entity using auto-assigned identity     *
*                      fails with duplicte INSERT SQL.         *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
A MapsId annotation in entity C (child) annotates a field p of
type P (parent). P uses auto-generated identity.
P-C is a bidirectional parent-child relationship.
During flush sequence, a row is created for P and flushed for
the database to assign an identity. When C is flushed, it
wrongly creates a row for P again while handling the field p
that points to parent.
This results in a commit which fails with a
DuplicateKeyException on P's table.

Problem conclusion

With this fix, code has been added to OpenJPA to properly
generate SQL when handling a Parent/Child relationship
which uses MapsID and auto-generated identity.

The fix for this APAR is currently targeted for
inclusion in Service Levels (Fix Packs) 8.0.0.7 and
8.5.5.1 of WebSphere Application Server versions 8.0.0 and
8.5.5.
